/*
 * $Log$
 * Revision 1.24  2005/05/05 09:46:11  cargilld
 * Update XSValue to handle float and double the same way the main library does, converting values to infinityr or zero, as the C ranges for float and double are less than the schema ranges.
 *
 * Revision 1.23  2005/04/22 20:02:34  cargilld
 * Use isspace instead of isSpace as data is char not xmlch.

 *
 * Revision 1.21  2004/12/23 16:11:21  cargilld
